Ethene and bromine water
WebIn fact, bromine is a very polarisable molecule - in other words, the electrons in the bond are very easily pushed to one end or the other. As the bromine molecule approaches the ethene, the electrons in the pi bond tend to repel the electrons in the bromine-bromine bond, leaving the nearer bromine slightly positive and the further one slightly negative. WebAn additional reaction happens between bromine and alkene. For instance, when ethene combines with bromine water, it forms 1, 2 dibromo ethanes. If the reactants are gaseous, the reaction must happen at room temperature (ethene). Even as bromine water solution combines with ethene, it loses its colour.
